Snowblower: Any one ever removed one of these metal keys? Need to change a roller bearing for the auger's main shaft
Original Message Nov 14, 2008 5:38 pm

My snowblower was groaning something awful when engaging the blower unit. I found a new bearing that matches the one that wore out. Now I need to get the old bearing off the shaft.
The bearing would slide right off if it is was not for this small rectangular metal key that slides into a slot on the shaft. Anyone ever deal with one of these?. Do I need a special tool? I have a Harbor Freight nearby with all sorts of strange inexpensive tools. If only I knew what to look for. If I ever do get the key out, how will I get it back in ?

Is the metal key a "one use" type of device. So I'll need to find a replacement? Maybe this is whey the bearing was never replaced sooner. Sorry for so many questions.

It's just a tight fit, sometimes not so tight. No slots or taper or anything. If it doesn't move
easily there might be some rust but it shouldn't be that hard to remove. I doubt you'll damage
it very much getting it out.

To re-install just tap it in on the side, not from the end. Put some grease on it
so it'll be easier next time.

Thanks, I think I get it now.

If you loose it you can get new ones at a Lawn and Garden centre. They charge a buck or two to cut a piece of the bar stock or you can get a bar and cut your own for less then $10. To cut it you just score one side of the bar and bend it. You can also use a dremel cutoff wheel.
